Browser Selector Build status

Small utility to launch a different browser depending on the domain of the url being launched.

Read the blog post about this here.

Setting Up

  1. Grab the latest release and extract to a folder somewhere on your PC.
  2. Open the BrowserSelector.ini file and customise paths to your browsers and domain patterns (see below).
  3. Run BrowserSelector.exe --register from this folder to register the tool in Windows as a web browser.
  4. Open the "Choose a default browser" screen in Windows (you can simply search for "default browser" from the start screen).
  5. Select BrowserSelector as the default browser.

So far, it has been tested on the following:

  • Windows 8.1
  • Windows 10 Pro


BrowserSelector.exe --register
    Register as web browser

BrowserSelector.exe --unregister
    Unregister as web browser

BrowserSelector.exe --create
    Creates a default/sample settings file

BrowserSelector.exe ""

BrowserSelector.exe [--wait] ""
    Launch, optionally waiting for the browser to close..

BrowserSelector.exe "" "" [...]
    Launches multiple urls

BrowserSelector.exe "my bookmark file.url"
    Launches the URL specified in the .url file.

BrowserSelector.exe "my bookmark file.webloc"
    Launches the URL specified in the .webloc (osx) file.

If you use the --wait flag with multiple urls/files each will open one after the other, in order. Each waits for the previous to close before opening. Using the --wait flag is tricky, though, since many (most) browsers open new urls as a new tab in an existing instance.

To open multiple urls at the same time and wait for them, try the following:

BrowserSelector.exe "url-or-file" "url-or-file" --wait "url-or-file"


Config is a poor mans INI file:

; Default browser is first in list
; Use `{url}` to specify UWP app browser details
chrome = C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
ff = C:\Program Files (x86)\Mozilla Firefox\firefox.exe
edge = microsoft-edge:{url}
ie = iexplore.exe
chrome_prof8 = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 8"

; Url preferences.
; Only * is treated as a special character (wildcard).
; Matches are domain-only. Protocols and paths are ignored.
; Use "*" for subdomains, not "*" as that would also match "".
[urls] = ie
* = ie

; Use my project-based Chrome profile = chrome_prof8
myproject.local = chrome_prof8

; if the key is wrapped in /'s, it is treated as a regex.
/sites\.google\.com/a/\.com/ = chrome_prof8 = chrome = edge


chrome = C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
chrome_prof8 = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 8"
  • Browser exes must be exact paths to the browser executable.
  • Arguments are optional. However, if you provide arguments the exe must be enclosed in quotes.
  • If there are no arguments, then the exe paths do not need to be quoted.

Special cases:

edge = microsoft-edge:{url}
  • For special browsers, you can include the {url} flag. This allows better control over the browser command-line arguments.
  • This is required when specifying UWP app's such as Microsoft Edge.
  • By default, the url is used as an argument when launching the exe. If the {url} flag is specified, it will not be added to the arguments. (In other words, it won't be added twice..)


There are two ways to specify an Url. You can use simple wildcards or full regular expressions.

Simple wildcards: = ie
* = ie
  • Only * is treated as a special character in URL patterns, and matches any characters (equivalent to the .* regex syntax).
  • Only the domain part (or IP address) of a URL is checked.
  • There is no implied wildcard at the start or end, so you must include these if you need them, but be aware that "microsoft.*" will not only match "" and "" but also "".

Full regular expressions:

	/sites\.google\.com/a/\.com/ = chrome_prof8
  • Full regular expressions are specified by wrapping it in /'s.
  • The domain and path are used in the Url comparison.
  • The regular expression syntax is based on the Microsoft .NET implementation.
